| Abstract: | The bridge section of 6 m×9 m on north secondary navigable span of Wuhan Erqi Yangtze River Bridge is located on the third terrace of the Yangtze River.As high variability in hydrogeological condition during construction period,the proposed construction method for the bridge foundation using steel boxed cofferdam is affected seriously.Based on the analysis of the form characteristics and applicability of common types of cofferdam in the shoal area and combining with the actual condition of the project,we adjust the construction method for the bridge foundation to steel sheet pile cofferdam to improve the construction efficiency and save the cost. |
